The makers of the popular board game Scrabble have added a new word to the official player’s dictionary.

Geocache beat out 15 other nominated words in the Scrabble Word Showdown to become the winning word that will be included in the upcoming fifth edition of Merriam-Webster’s Official Scrabble Players Dictionary.

What is geocaching?

Geocaching is a real-world, outdoor treasure hunting game using GPS-enabled devices. Participants navigate to a specific set of GPS coordinates and then attempt to find the geocache (container) hidden at that location.
